Original ArticleUtilization of colonoscopy in the United States: results from a national consortium
Section snippets
CORI
Practice sites throughout the United States joined the CORI consortium from 1996 to 2001. Participating sites agreed to use a structured, computerized report generator to produce all endoscopic reports and to comply with quality-control requirements. The data file from the report is transmitted electronically to a central data repository, the National Endoscopic Database. All patient and physician identifiers are removed from the data file before transmission from the local site to protect both
Results
We received complete colonoscopy examination reports from 146,457 unique patients during the study period. Reports were received from private practice settings (68%), academic universities (20%), and Veterans Affairs (VA) medical centers (12%).
Discussion
This is the first study to characterize the utilization of colonoscopy in diverse clinical practice settings. Characterization of current endoscopic practice patterns can help inform decisions with regard to resource utilization. Unlike claims databases, the CORI repository provides a wealth of clinical information with regard to patient symptoms and findings. Unlike the Medicare database, the repository reflects the full spectrum of endoscopy across all age groups. Unlike research from
